The countDown function accepts a total time T in seconds and integer steps. It displays T, then waits half that time and displays the remaining time, continuing to halve and display the time after each wait until only 1/2^steps of the original time remains. At that point, it waits the final time, displays 0 and emits an audio tone.

1. In scilab Write a function named countDown that accepts a total time T in seconds and displays
the time remaining after half of the previously displayed time has elapsed as described below.
The function should also accept an integer Steps as also described below. The function should
immediately display the value of T, then wait T/2 seconds before displaying the value of T/2. It
should then wait T/4 seconds and display the value of T/4, etc. This should continue until only
1/2Steps of the original time remains, at which point it waits for the this remaining time, displays
a 0 and emits an audio tone.
Solution
Solution: See the code below:
------------------------------------------
function countDown(T,steps)
time=T;
while time > (0.5*steps)
disp(time);
time=time/steps;
sleep(time*1000)
end
sleep(time*1000);
disp("0");
beep();
endfunction
countDown(20,2)
